Before you go out and spend your $200, I would recommend taking an afternoon or a weekend and taking inventory.
I'm not saying you need to tear your house apart from floorboards to roof, but definitely go through your medicine cabinets, go through your fridge/freezer, and go through your pantries and storage areas.
Throw out all the expiered stuff and make notes of what you will need if power goes out for a few days or a week.
Make sure you have flashlights (and batteries), make sure you have at least a basic first aid kit with things like bandages and disinfectants, make sure that you have blankets and spare clothing for any kinds of weather situation, make sure that you have some canned goods and water (or a good filter), make sure that you have something for home defense.
If you have all of that covered then definitely move on to investing in something like a good BOB to store your supplies.
If you have all of that, then I would look into investing in projects around your house. Maybe starting up a garden, or insullating your windows to save on energy costs, or purchasing a generator, or remodeling a cabinet or room so that it can store materials more efficiently.
Just some suggestions, you sound like you're way ahead of the game from a financial resources standpoint. Take things one step at a time and just do a little each day and down the road you'll be amazed at how far you have progressed.
Last thing I'll say is... you said that you "only" have 2 glocks? No offense, but you only have two hands so I don't understand how having more guns is really going to benefit you? Having drinking water and canned goods are much more important than assault riles and bullets.
I mean, if you are talking about investing in a rifle for hunting then I understand, but, assuming you have proper training 2 handguns should get you through most situations.
I dunno, a lot of people on this forum probably disagree with me, but having an aresenal of guns is one of the last things on my survival checklist. (though I will say that having one gun and proper training was one of the first things, and having a backup firearm is definitely a reasonable prepping item)
